D-Link 140W Redundant Power Supply

The D-Link DPS-500A is a redundant power supply that delivers up to 140 watts of backup power to compatible D-Link Fast Ethernet and Gigabit switches. By taking over instantly when a switch’s internal supply stops working, it shields the network from unexpected downtime and keeps data, voice, and video traffic moving without interruption.

This unit connects directly to the designated power port on supported switches, so no configuration changes are required. A housing made of solid metal protects the internal components, while front-panel LED indicators give at-a-glance confirmation of active or standby status. The wide input range of 90 to 264 volts at 47 to 63 hertz means it can operate reliably in offices, wiring closets, and data centers around the world.

Deployment is flexible. Use the DPS-500A as a standalone module on a shelf, or snap it into an optional rack-mount chassis to centralize redundant power for multiple switches. Either way, installation is straightforward: connect the power cable, attach the switch’s redundant power cord, and the system is ready.

The DPS-500A is a practical choice for small and medium businesses, branch offices, or any organization that relies on constant network access for services such as VoIP calls, IP surveillance, or real-time data synchronization. Adding this power supply extends the life of existing D-Link switches and adds a layer of protection that guards critical applications against unexpected power failures.
